1. Adrenalin when mixed with olive oil 1:100 and injected subcutaneously into a catfish will produce a marked pale spot and a general blanching of the whole fish. The general blanching will disappear in about a day. The pale spot may last 3 to 4 weeks. 2. Injections of adrenalin in oil 1:1000 to 1:10,000,000 cause the formation of only pale spots in catfishes. Adrenalin in oil 1:100,000,000 has...

A mineral medium for studying the growth of Nitrosomonas europaea was developed and examined. The medium was defined in terms of chemical speciation by using chemical equilibrium computer models. The medium significantly increased the metabolic activity of the organisms compared with previously developed media, yielding a specific growth rate as high as 3.0 day (generation time, 5.5 h). The spe...

Increasing the level of urea and uric acid is an associated complication of diabetes mellitus. Many spices and herbs are known to be hypoglycaemic. Olea europaea belonging to the family oleaceae is widely used in herbal medicine for the treatment of diabetes. The present study was carried out to investigate the role of the alcoholic extract from leaves of olive on level of urea and uric acid in...

An exploratory effort to selectively detect the presence of a nitrifying bacterium, Nitrosomonas europaea, successfully demonstrated the fundamental utility of an enzyme-based immunoassay protocol. The applied polyclonal antibody test seemingly offered a marked improvement over the available analytical options, including plating, activity, and fluorescence immunoassay techniques. Following an i...

Wild olive crude extracts were screened for antibacterial activity against five different bacterial human pathogens. Four different solvents were used for the extraction. Antibacterial activities of plant extracts were compared with those of standard antibiotics. The capacity of the extracts and antibiotics were evaluated on the basis of their capacity to inhibit the growth of pathogenic bacter...

The nonconventional yeast Yarrowia lipolytica degrades very efficiently hydrophobic substrates to produce organic acids, single-cell oil, lipases, and so forth. The aim of this study was to investigate the biochemical behavior and simultaneous production of valuable metabolites such as lipase, citric acid (CA), and single-cell protein (SCP) by Yarrowia lipolytica DSM 3286 grown on various plant...

As published initially in this same journal in 2000, the lipid extract of Perna canaliculus (New Zealand green-lipped mussel; Lyprinol) is known for its anti-inflammatory effects in animal models and in human controlled studies (arthritis; asthma). As a follow-up of its effects on pain in a rat model of adjuvant-induced arthritis (ALA), we studied its effects on the production of cytokines know...

The ability of lipolytic yeasts to grow on olive mill wastewater (OMW)-based medium and to produce high-value compounds while degrading this waste, was tested. OMW collected from three-phase olive mills from the North region of Portugal were characterized and used. OMW with COD ranging from 100 g L(-1) to 200 g L(-1) were supplemented with yeast extract and ammonium chloride. Studies of OMW con...
